USES: Guaifenesin helps to loosen mucus. Phenylpropanolamine is a decongestant. This combination medication is used to relieve nasal congestion and symptoms associated with the common cold, allergies, hay fever, sinusitis and other respiratory illnesses.

HOW TO USE: This medication is best taken with a full glass of water after a meal or snack. The tablet can be broken in half. However, the whole or half tablet should be swallowed whole. Do not crush or chew the tablet before swallowing it. The long action will be destroyed and the chance of side effects will be increased. Do not increase your dose or take this more often than directed.
